阴离子的

It is interesting that (1)hyperconjugation of the solvent's CF3-donor group prefers H4/H5 of BMI cation to H2, which can be explained by the steric hindrance of PF6 anion;(2) the various-temperature 19F spin-lattice relaxation times (T1) of CF3 show phase change, e.g.

藉由分析阳离子和三氟乙醇的扩散速率求得DD值，可以看到改善在乙醇形成大的基团，产生较强的分解，三氟乙醇的性质利用19F、1H化学位移，得到(1)CF3和阳离子H4、H5形成超共轭大於对H2，因为立体效应的关系，而藉由19F迟缓时间的数据，三氟乙醇展现相变化，由一到两各堆叠的离子对，和一个阴离子形成超阴离子的情形，因为溶剂而开始崩解，在继续分解可得到自由的阴阳离子。
